Starch phosphorylase is another enzyme, which
mediates the phosphorolytic cleavage of terminal glucose units at the nonreducing end of
the starch molecule using inorganic phosphate, thus releasing glucose-1-phosphate. The
amylopectin molecule is also degraded in a similar manner to amylose, but also involves
the action of debranching enzymes, which cleaves the α-1,6-linkages in amylopectin and
releases linear units of the glucan chain
